Page1 UCA Newsletter of the Maroochy Wetlands Sanctuary Support Group Inc. President s Report for October 2017 October 2017, no.10 There has been another good downpour of rain in the wetlands that will be great for all wetland plants during the flowering and food producing season. An Owlet Nightjar has been nesting near the boardwalk and because of the disturbance to it from passing visitors, we have had two Owlet- Night jar nesting boxes and two Microbat habitat boxes donated by friends of the Sanctuary. These will be erected as soon as possible. Council has supplied us with the traffic count down the boardwalk for August. I think they will be of interest to you, as they were to me. Peak Day 152, Minimum Day 11, Average Week Day 44, Average Weekend 57, Total for August is 1438. At long last the display signs for within the Sanctuary are complete and should be erected by Council shortly. The Landcare Group has done some new planting along the boundary of the reserve and the Council has granted us $5000 to employ contractors to eradicate major infestations of Morning Glory and Mile- a - minute on the southern boundaries of the reserve. Council has also done some painting and repair work on the toilet block. Vice President Derek conducted a very successful Planning meeting for 2018. More of this later. Look forward to seeing you around the reserve sometime. Robin.
Page2 At the Sanctuary September 2017 Robyn Howard Our final scheduled free guided walk for the year was on 3 rd September, with fewer participants than for the previous events. The results of the lack of rain were sad to see. So much vegetation was wilting, so many leaves were dropping, some plants were obviously at the end of their resilience. Not many birds were nesting at a time which is normally the height of the breeding season because they had bred earlier, and because the insects necessary to feed the young were just not available. One bird which was behaving unusually was the Noisy Pitta. They visit during autumn and winter and are usually gone by spring, but on returning to the Information Centre, I heard several calls from at least one bird after midday. Their normal calling times are early morning or late afternoon and dusk. I had heard the bird give a single call a couple of days earlier so they must have been just a little later leaving the area. The River Mangroves were beginning their white floral display. Just after mid-month, I decided to do a walk in the late afternoon, extending through sunset until after dark. I was disturbed that I encountered four Brown Hares on the drive, two lone animals plus a female with a half-grown young. They are not natives and while they are not the pests that rabbits are, it would be a shame to see their numbers build up. The carpark was quieter than on most visits, so some birds were preparing for their night s rest. A broken flock of around 30 Rainbow Bee-eaters flew over, and later as I traversed the open section of boardwalk in the mangroves, 26 Yellow-tailed Black-Cockatoos were in smaller groups heading to their roosts. At the bird bath, a Spectacled Monarch, a Grey Fantail and a Rufous Fantail shared early evening ablutions. As I strolled down the boardwalk, I noticed several birds still active both feeding and calling Eastern Yellow Robins, White-throated Treecreepers, Scarlet and Lewin s Honeyeaters, Bar-shouldered Doves, and a Rufous Whistler. It was cloudy with a new moon, so I was surprised by the amount of light available. It is so beautiful just observing the differences from activities in the bright light of day and the changes in calls and sounds. Even when it was becoming dark, several species were still calling, including both the Azure and Collared Kingfishers, the Mangrove Gerygones, Brown Honeyeaters, and both the fantails. My attention was also drawn to movement along the edge of the water under overhanging Grey Mangroves. A Royal Spoonbill was rhythmically swing its head from side to side, bill open, occasionally snapping it shut then throwing its head back to swallow. In the stillness, the clacking of the Pistol Shrimps hidden in their muddy burrows was penetratingly loud. One of the main purposes of this particular visit was to check whether the pair of Large-tailed Nightjars which had moved to the area two years previously was still resident, so I ensured I was settled quietly at the crab-viewing platform before complete dark. On the dot of 6:00 p.m., I heard the first call and the bird continued the single note call incessantly for six minutes before its mate responded with its chop-chop call, uttered several times. The first caller changed to the similar call, then a couple of other gentle calls. Shortly, I heard a bird directly
Page3 across the river, then later another bird down-stream in the sanctuary, and another even further down-river. A sixth bird called from inland. This species only extended its known southern range in 2014, so numbers have increased quickly. I wonder how much further south their range has extended. During this time, a lone silent Australian Owlet-Nightjar did a single circuit from the mangroves along the river, then disappeared again. The pair has nested again, but unfortunately chosen the same site as their unsuccessful nesting last year. The atmosphere as evening falls is so beautiful. No boats or jet-skis on the river, only the sounds of the changing activities of nature. The diurnal birds falling silent and going to their rest, the nocturnal birds awakening and commencing the search for sustenance, the insects with their stridulations, the nocturnal animals and reptiles rustling the leaf-litter and foliage, gentle breezes making their own melodies through the tall vegetation. Brown Hare in the forest.

Photo: Sandra Harald Australian Owlet-nightjar Nocturnal birds at the Maroochy Wetlands Sanctuary include Tawny Frogmouth, White-throated Nightjar, Large-tailed Nightjar, Australian Owlet-nightjar, and Southern Boobook. Other owls have not been definitively identified. The Australian Owlet-nightjar at 21 to 25 cm is Australia s smallest nocturnal bird. There are two colour forms, rufous and grey, the latter being the common form. The strongest markings are a central black bar on the head and two black bars which arise above the eyes and meet on the back of the neck. The bill is broad, ideal for catching insects in flight. Bristles at the base of the bill assist with sensitivity and funnelling into the gape. Primary wing feathers and the tail are strongly barred while the body feathers sport fine soft attractive barring.
Page6 The Australian Owlet-nightjar is common, though not often seen. It uses any well treed areas with sufficient suitable hollows which it requires for both roosting and nesting. A fortunate observer may sight a bird sunning at the entrance to its hollow during the day. Pairs form bonds and maintain the territory the whole year. A nest is created by adding green leaves to the base of the chosen hollow. Aromatic leaves may discourage pest insects and mites. Eggs are incubated for around 28 days, both parents then feeding the nestlings for a further 28 days before they fledge. The fledglings are fully dependent on their parents, gradually acquiring hunting skills and knowledge of food resources over the next few months before they can become fully independent. In suburbia and young forests, nest boxes can provide an alternative nesting site. Calls are occasionally heard during the day, but mostly at night, especially when there is little moonlight, continuing spasmodically until the pre-dawn. Most calls are churs repeated two or three times, but one call is a somewhat sneeze-like choo. Foods consist of insects which may be taken in flight, off leaves or tree limbs, or from the ground. Prey includes beetles and grasshoppers, but most insects could be included in the diet. When chasing insects on the wing, flight is silent and erratic. One evening at the Maroochy Wetlands Sanctuary, I watched an Australian Owlet-nightjar complete 7 or 8 circuits of an open area before moving on to patrol another area. At the Maroochy Wetlands Sanctuary, there are several resident pairs and some good fortune may afford sightings in the melaleuca forest or the mangrove habitat near the river, or sometimes along Sports Road. webpage: www.marcoochywetlandssupport.org
Page7 Our group had a planning morning this week at the Wetlands on Saturday 14 October. We do this each year to review what we have achieved in the year just past and to look forward to what we would like to achieve in the year ahead. Because visitation to the Wetlands is seasonal (mainly in the cooler months when there are fewer biting insects around) we are planning now for the 2018 season. In the year just past, we had several initiatives that were very successful. In particular the Eco- Hunt run in conjunction with Sunshine Coast Council during the July-August school holidays encouraged a great number of families to visit the Sanctuary and enjoy all there is to offer. We have agreed with Council to repeat this activity in mid-2018. One of the biggest limitations for our group is the small size of the active membership. Whilst subscribing members are very welcome there are many activities that cannot be carried out for lack of people willing to contribute their time as well. In the year ahead, our main effort will be directed towards building membership and encouraging more people to take up an active role. To that end we have agreed on what we are calling the B3 project. B3 represents Birds, Bees and Bats. All of these are present in the Sanctuary in varying degrees. There are many bird species, some year-round and others migratory. Native bees are also present as are micro bats which are the ones we will be targeting. As part of this project we will seek to engage the local community to understand more about the B3s and the good that they do around us. Hopefully some of those people will engage with us in these activities. Do you know that micro bats eat every night a very great number of mosquitoes? Wouldn t it be great to encourage more of them around Bli Bli? Perhaps we could build more habitat for them. To find out more about micro bats go to: https://www.ehp.qld.gov.au/wildlife/animals-az/micro-bats/ More information will be published as we further develop our project.

Page8 Bird Observers Report Inglewood Area 3 rd, 4 th, 5 th, 6 th & 7 th October 2017 The weather for the Inglewood region had been dry for months, and the possibility of bush-fires had been in mind, but the day and night before the commencement of our excursion, some good rains fell. In fact, the flat desert areas were water from horizon to horizon at first. The forecast each day was for rain or storms, but on every occasion, just as we thought we were about to receive a heavy downpour, the clouds changed course and circled around us. We chose as many different habitats as we could find, several along the Macintyre Brook or Bracker Creek, and beside Lake Coolmunda, though a fishing competition spoiled both our birding there and the camping area where we stayed, with some of the fishing group drinking and noisy until after 3.00 a.m. The desert area which had been great before the rain was poor later on, but otherwise we had brilliant birding. In some spots, the birds just seemed to come to show themselves off, and we found more species than we could have hoped for. It was a long drive out to Coolmunda and Inglewood, and on one day we traversed 120 kilometres visiting our sites, but every little bit of travel was well worth the effort. One of our main aims was to find birds which we do not see in our coastal areas, and we certainly achieved that aim. We saw so many birds at some sites that we did not make it to all our planned areas, but that mattered little when we were having such a great time. Sacred Kingfishers, Restless Flycatchers, Willie Wagtails and Red-winged Parrots seemed to turn up at almost all places. Nesting was in full swing, with some birds building, some sitting on eggs, some feeding nestlings, and some feeding fledged young. The nests of the Yellow-rumped Thornbills posed an identification problem as they were structured quite differently from those in other areas. Favourite sites were Durikai Waterhole, the Water Reserve and Recreation Area, Yelarbon Lagoon and Reibelt Road. Favourite sightings were our first White-throated Needletails and Forktailed Swifts for the season, Pink-eared Ducks, Plum-headed Finches, Blue Bonnets, Zebra Finches, Rufous Songlarks, Brown-headed Honeyeaters, and some really special birds such as the juvenile Pallid Cuckoo (none of us had found a juvenile before), Black-eared Cuckoo, Hooded Robins, Red-capped Robins, Horsfield s Bushlark (performing a courting flight),white-winged Fairy-wrens, and the Diamond Firetail which calmly fossicked around allowing all to have wonderful viewing. In all, we found 161 species, with 6 of those being heard only (h). That is an amazing tally!
